/* ═══════════════════════════════════════════════════════════════
   Qallak — site design system v4 · matched to the Qallak app
   One shared system for every page (landing + inner pages).
   Palette, type and surfaces mirror lib/core/theme/selam_colors.dart:
     primary blue #2563EB · teal accent #14B8A6 · amber #F59E0B
     light = soft gray #EEF0F3 · dark = deep navy #0B1120
   Type: DM Sans everywhere (app uses DM Sans for display + body).
   No all-side borders — tonal fills + soft shadows (selamCard look).

   NOTE ON TOKEN NAMES: the design-system token names below
   (--roast / --leaf / --honey) are legacy from the earlier editorial
   theme and are referenced ~40× here and inline in index.html.
   They are kept to avoid churn but now hold APP colors:
     --roast = app primary blue   --leaf = app teal   --honey = amber
